POINTS TO NOTE DURING OPERATION

If none of the functions can be used, check the diagnostic trou-
ble codes, and after carrying out any necessary repairs, repeat
the operation. If an incorrect password is input five times in a
row, the ETACS-ECU judges that an unauthorized operation is
being attempted. Start-prevention mode will be set, and engine
operation will stop and all special functions will be disabled. If
the ignition switch is turned to "ON" position and left in that
position for approximately 16 minutes, "Unauthorized opera-
tion, start- prevention mode" will be cancelled.

KEY ID REGISTRATION

All ignition keys can be registered with diagnostic tool
MB991958. Additional ignition keys can be registered with
diagnostic tool MB991958.

.

CAUTION

To prevent damage to diagnostic tool MB991958, always

code is set, resolve the problem beforehand.

have been previously registered in the ETACS-ECU to be
erased. All keys need to be registered. Those which have
been registered before should be on hand before using this
function.

• If registering more than one key, do not disconnect

diagnostic tool MB991958 halfway through the registration
